#144601 - Trying to understand
Responding to: ???'s previous message
That ugly word rears its head again ! What kind of breadboard ?

Its just a normal bread board, I think a photograph wont help, but, lets try, its free!?




(Yes, it is a lunch box)


May I say what a lovely job you have done in presenting the problem to us. Perfect !

Are you serious? Thanks!


I once had a chat with a manufacturer of digital mixing consoles ... To give an analogy, this mechanism imitates the slack you have on an analog potentiometer...

You mean like a deadzone? If it changes +1 or -1 it ignores. Once someone told me as "deadband algorithm". I will give a try, just dont know: How to get a module (ex: |X-Y|=positive number ) of number in ASM?... and what is "bseg", "dbit", "dseg" and "cseg" seen in your code.


..the i.cs are creating noise on the power simply by operating, so you need to have capacitors on the power to take care of this

I using 2.2u, 1000u and 0.47u parallel to batteries.



ADC is 8 bits and I just need 7 bits, I dont think I want TOO MUCH from ADC

What do you think about my circuit, it is right? Its my first microcontroller project, please tell me what you think about it (good or bad) or how to improve it. I just dont put it on a PCB because im not satisfied with it.

What do you think about delay time I'm using between end of conversion - input port change - start of new conversion?


Thanks for all help.

PS: You can say "Damn noob".
I feel bad always posting questions asking for help and not helping the others because I dont know anything. Sorry.
